            Bug ID: 109152
           Summary: VMProcess.<init>()/destroy() affect thread interrupt
                    flag
           Product: classpath
           Version: 0.99
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: classpath

  Target Milestone: ---

VMProcess.<init>()/destroy() affect thread may disable the interrupt flag.

Both methods contain a block of code like this for performing an
uninterruptible wait:


----------------------------------------------------------------
    while (state != TERMINATED) /* or == INITIAL */
      {
        try
          {
            wait();
          }
        catch (InterruptedException e)
          {
            /* ignore */
          }
      }
----------------------------------------------------------------

If the thread is already interrupted when that point is reached, or if it is
interrupted while waiting the interrupt flag will be stay cleared after the
condition is fulfilled and the rest of the code executed by the thread won't
have a chance to know that it has been interrupted.
